• Groin hernias: Inguinal, femoral and obturator (Laparoscopic and open)
  • Abdominal wall hernias: Umbilical, epigastric and other hernias (Laparoscopic and open)
  • Complex recurrent and incisional hernia surgery (Laparoscopic and open)
  • Repair of divarication of recti (Laparoscopic and open)

Professor Amir Nisar has been a contributor to the National Institute of Clinical excellence (NICE), in United Kingdom, leading to NICE guidelines produced for Laparoscopic Inguinal (groin) Hernia surgery in 2001 and September, 2004.

He has several innovative approaches/techniques in TEP (Totally Extra Peritoneal Hernia repair) and TAPP (Trans Abdominal Pre Peritoneal hernia repair), making the surgery simple and safe for complex cases. His current focus in general and hernia surgery is Laparoscopic, Needlescopic and Miniscar/Scarless hernia repairs, offering patients quicker recovery and less post-operative pain.

Heartburn/Gastro Oesophageal reflux disease (GORD/ GERD) surgery

  • Laparoscopic hiatus hernia antireflux surgery
  • Laparoscopic hiatus hernia antireflux re-do surgery
  • Laparoscopic hiatus hernia antireflux re-do surgery after previous bariatric procedures (weight loss surgery)
  • Laparoscopic Heller’s cardiomyotomy for achalasia of oesophagus

Professor Amir Nisar has performed laparoscopic anti-reflux surgery for more than 22 years. He has worked in high volume tertiary referral centers for oesophagstric and hiatus hernia surgery for 20 years. He has had exposure to straight forward, complex and re-do surgery cases for the management of gastro-oesophageal reflux disease requiring surgical intervention. He has performed this surgery in these high-volume specialist centers for more than two decades, leading to his several innovative approaches for simple and complex scenarios.

He established an Oesophageal Physiological studies laboratory in 2007 and was the director of the lab for 10 years.

He has regularly performed anti-reflux surgery in international courses and conferences in the United Kingdom, Europe and Asia.

He was one of the selected few surgeons, who operated on the National reflux trial conducted in United Kingdom in late 1990s. He has established many centres in United Kingdom and other countries by proctoring the surgeons in their hospitals.

Professor Amir Nisar was one of the two surgeons to perform the first ever 20 laparoscopic Nissen’s fundoplication operations, as day cases, with excellent outcomes.

He developed a three 5mm port technique for Hiatus hernia surgery and presented this in United Kingdom and European international meetings and courses. He is currently further minimising trauma in hiatus hernia surgery is Laparoscopic, Needlescopic and three port hiatus hernia repairs; offering patients quicker recovery, better cosmesis and less post-operative pain.

Gallbladder surgery

  • Laparoscopic biliary surgery
  • Laparoscopic gallbladder surgery (Laparoscopic Cholecystectomy)
  • Laparoscopic common bile duct surgery & intraoperative choledochoscopy
  • Complex laparoscopic re-do biliary surgery
  • Laparoscopic transgastric pancreatic cyst gastrostomies

Professor Amir Nisar performs this common surgical operation in an innovative fashion with many special considerations to keep the number of incisions on the abdomen to a minimum, thus offering excellent cosmesis, less post-operative pain and quicker recovery.

The operation of gallbladder surgery (Laparoscopic Cholecystectomy) though common, carries a risk (1 in 200) of damage to the common bile duct. Professor Nisar uses a very safe but rarely used technique that he learned from his mentor consultant surgeon in early 90’s, which helps to minimize the risk of damage to common bile duct. This has helped him to achieve good results in thousands of cholecystectomies, as well as the many complex cases that he has performed to date.

While serving in the executive council of ALSGBI (Association of Laparoscopic Surgeons of Great Britain and Ireland), he was a part of the team advising the health department on the status of Laparoscopic Cholecystectomy and Single Incision Laparoscopic Surgery (SILS), and recommendations regarding the surgeons performing this operation in United Kingdom.

In the United Kingdom, he was among the leading surgeons performing the surgery as a day case and for ‘hot gallbladders’ (with acute cholecystitis), achieving excellent results and minimal post-operative complications.

His current focus in general and gallbladder surgery is Laparoscopic, Needlescopic and Miniscar/ScarLess/LessScars cholecystectomies, offering patients quicker recovery, less post-operative pain and excellent cosmesis.

Weight Loss Surgery / Bariatric Surgery (first time and complex re-do surgery)

Professor Nisar’s interest in bariatric surgery spans more than three decades with extensive work, study, visits to renowned weight loss (bariatric/metabolic syndrome surgery) institutions, and attendance at courses, conferences and meetings.

Professor Nisar strongly believes that excessive weight gain in individuals is a multifactorial and long-term issue and must be handled sensitively, respectfully, diligently, with shared understanding and mutual trust between the patient and the team to achieve long-term benefits from any surgical intervention.

He has worked in centres of excellence in Bariatric Surgery in the United Kingdom, all of which have a long history of performing such surgeries. These centres not only saw new patients and offered them the most modern multidisciplinary management of their condition, but also treated some of the rarest complications, which may present many years after the initial surgery and success in weight loss. Understanding the short-term needs and long-term issues and their solutions makes Professor Nisar a comprehensive bariatric surgeon for his patients.

He has successfully set up bariatric services with dynamic and dedicated multidisciplinary teams in eight NHS and private hospitals in the UK.  He has managed to achieve excellent results over the years through appropriate assessment, communication and appropriate bespoke surgical interventions in his bariatric patients.

In addition to the primary (first time) bariatric surgery, he offers excellent results for re-do surgery after the bariatric procedures and has supported his colleagues in different institutions.

He has special interest in anti-reflux surgery and is happy to assess and offer management to patients who have reflux after sleeve gastrectomy or proximal gastric bypass operations.

Gastrointestinal cancer surgery

  • Minimally invasive (Laparoscopic) oesophageal surgery (benign and cancer)
  • Minimally invasive (Laparoscopic) gastric surgery (benign and cancer)
  • Laparoscopic surgery for stomach GIST (Gastro Intestinal Stromal Tumours)
  • Laparoscopic cancer surgery of small and large bowel

Professor Amir Nisar’s experience in gastrointestinal cancer surgery spans over a period of 30 years. He is highly experienced in both open and laparoscopic surgery for all gastrointestinal cancers.

Professor Amir Nisar regularly performs these operations at an international level, teaching other experienced surgeons innovative laparoscopic techniques to deal with these cancers.

He also pioneered laparoscopic and thoracoscopic Oesophago-Gastric and Colorectal cancer surgery cadaveric courses in United Kingdom in 2008 to train surgeons in this complex cancer surgery.

He is working on further minimising the recovery and recuperation period in laparoscopic and open surgery operations. Early mobilisation and various other supports offered to the patients according to the principles of enhanced recovery discipline, helps the patients to recover quicker with shorter hospital stay and early return to activity and work.

General surgery

  • Splenic surgery (Partial and total Laparoscopic Splenectomy)
  • Surgery for diverticular disease
  • Laparoscopic adrenalectomy
  • Laparoscopic surgery for adhesions after previous surgery
  • Day case surgery for simple and intermediate procedures
  • Haemerrhoids, fissures, pilonidal sinus, cysts. Ingrown toe nails and lipomas

Professor Amir Nisar’s extensive experience in these and other surgical conditions over the last 35 years helps him to manage these conditions with an approach most suited to the patient’s needs with excellent results. He prefers to offer bespoke treatment to his patients, managing the the conditions with simplest of measures and avoiding unnecessary surgical interventions in many simple cases.
